I am an immunologist studying host immune responses during malaria and visceral leishmaniasis, two important human infectious diseases. I aim to identify immune responses that promote safe and effective control of parasite growth and distinguish them from
Development Of Autoimmune Pathologies In Response To Cancer Immunotherapies
Funder

Funding Amount
$408,768.00
Summary
Cancer immunotherapies (CIs) boost a patient’s own immune response towards cancer, providing long-term survival benefits. However, in some cases, CIs imbalance immune activity, leading to aberrant activation against self. This is observed clinically as a broad spectrum of autoimmune syndromes including those affecting the endocrine system. This study will investigate the mechanism by which endocrinopathies develop in response to CIs, offering new strategies for identifying susceptible patients.
T Cells: Their Impact On HIV Evolution And Their Regulation In Influenza

Summary
The T cells of our immune system are critical defenders against viral infection. It is vitally important to understand what stimulates these cells so we can better target them against globally important viruses, such as HIV and influenza - infections that kill millions per year. We need to understand what genes in the T cell turns them into effective killers and which part of these viruses elicits the most effective T cell response. We can use this knowledge for vaccine development.
Polysaccharide Biosynthesis As A New Drug Target In Leishmania Parasites

Summary
Leishmania are protozoan parasites that cause a number of important diseases in humans, afflicting more than 12 million people worldwide. There are currently few drugs that target infectious disease causing stages of these parasites. We have recently shown that Leishmania parasites accumulate a highly unusual sugar polymer when they infect mammalian cells, which appears to be important for infectivity. In this proposal , we will investigate how this sugar polymer is made, identify enzymes involv ....Leishmania are protozoan parasites that cause a number of important diseases in humans, afflicting more than 12 million people worldwide. There are currently few drugs that target infectious disease causing stages of these parasites. We have recently shown that Leishmania parasites accumulate a highly unusual sugar polymer when they infect mammalian cells, which appears to be important for infectivity. In this proposal , we will investigate how this sugar polymer is made, identify enzymes involved in its synthesis and develop new chemical tools for generating highly specific inhibitors of Leishmania sugar biosynthesis. This project will provide new insights into processes that are essential for the survival and infectivity of an improtant group of human pathogens, and lead to the development of new classes of enzyme inhibitors with anti-parasite activity.Read moreRead less
Characterisation And Therapeutic Targeting Of Molecular Pathways That Promote Breast Cancer Metastasis To Bone

Summary
Breast cancer that has spread to bone cannot be cured. Using the most clinically relevant model of breast cancer available we have identified that tumour cells growing in bone need to suppress immune elimination (by suppressing the Type I interferons) and invade through the bone tissue (by activation of cysteine cathepsins). Studying the functional role of these pathways will provide novel insight into the mechanisms of breast cancer spread to bone that can be augmented therapeutically.
